You can use source material instead of LLMs for all of this.

"Is Bob Geldof's hair blue?" -> Search for Bob Geldof -> Look at images of Bob Geldof.

Intro programming topics can be found at the documentation of the website. Your searching query might be "[programming topic] getting started" and usually if it's a package or a tool there will be documentation. If you want good documentation on web dev stuff that isn't w3schools or geeksforgeeks you can use MDN documentation.

Or, if you really want a general overview there's probably a YouTube video about the topic.

Additionally appending "reddit" to a search will give better results than SEO junk. There are always ways to find quality information via search engines.
